The piston rod 2|J'isof sufcientlengtnto extend through the enginecylinder 2`ar1d through. the metal sleeve or liningZI before it isinserted within the engine cylinder 2. The `lower endol"1 the pistonrod* 2ll"is'threaded,` as at 22 and isf.' adapted to receivea securingnut` 23 threadable"` thereon.

The metal sleeve orflin'mg 2I isformed about its'upper end witha'laterally extending peripheral positioning flange A2lil which willseatagainst1 thelower surfaceof `the head memberfiwhen` in position forinsertion within the engine cylinder 2, said iiange--Zll being adaptedto be receivedl within the annular peripheral groove or seat 255" formedin the enginefblock rI about the upperA end of the cylincler'Z.`

Very often a metalsleeve Aor `lining `2 I is somewhat longer than thelength Vof the engine cylinder 2 into which` it is to be inserted, andwill` extendbelow the same. when` inserted within the cylinder.

To provide for these variations in the lengths panyingV drawings to4designateJ corresponding 554,01 the metalsleeves'or inserts 2I, thereispro'- parts;

of metal or any other suitable material, having a cylindrical seat orrecess 21 formed in its upper surface of a similar diameter to thediameter of the engine cylinder 2. A peripheral upstanding supportingange 28 is formed about the seat of the adapter body 2G with the openingof the cylinder 2 and said recess 21 being in vertical and axialalignment. A centrally disposed vertical bore 29 is formed through thecylindrical adapter body 26 to permit the piston rod 26 to slide freelytherethrough as the sleeve or lining 2| is being inserted within theengine cylinder 2. Three equally spaced, circumferentially disposed,threaded bores 36, 3| and 32 are formed through the adapter body 26 incircumferential arrangement being disposed between wells or seats 33, 34and 35, adapted to receive the three coil springs 36, 31 and 38.

A guide disk 3S is provided with a central vertical bore 4 6 throughwhich the piston rod 26 will pass, andA with three circumferentiallydisposed bores 4 I, 42 and 43 extending through the disk for receivingthe three guide pins 44, 45 and 46 which are headed, as at 41, and arescrew-threaded, as at 48, on their lower extremities for threadingthrough the threaded bores 36, 3| and 32 in the adapter body 26.

It will therefore -be seen from Figure 2 of the drawings that the coilsprings 36, 31 and 38 which are seated in the wells `33, 34 and 35 willsupport the disk 39 partially within the cylindrical seat or recess 21formed in the upper surface of the adapter body 26 and partially withinthe hollow cylinder or wall 2, while the three guide pins 44, 45 and 46will guide the vertical movement or adjustment of said guide disk 39.The guide pins 44, 45 and 46 being externally threaded through thethreaded bores 4|, 42 and 43 through the adapter body 26 will permit ofadjustment of the guide disk 39 with respect to said cup-shaped body 26.

From the foregoing description, the mode of operation will be asfollows: The hydraulic power cylinder 4.with its piston supportingpiston rod extending through the head 5 and neck with the packing gland49 threaded about the lower end of said neck is placed in position forthe sleeve or lining 2| to be telescoped over the lower end of thepiston rod 26 to seat on the head 5, and the piston rod will be inserteddownwardly through the cylinder V2 inthe engine block I, as clearlyillustrated in Figure 2 of the drawings. With the piston I3 near thebottom of the hydraulic power cylinder 4, the lower end of the pistonrod 20 will extend considerably below the lower end of the enginecylinder 2, and the guide disk 39 and cylindrical adapter body 26 willbe telescoped over the lower end of the piston rod with the upstandingflange 28 in contact with the lowersurface of the block I, being securedagainst aV piston rod carried abutment means, herein shown as the nut23. In this position, the guide disk will be resiliently held inelevated position partially within the recess 21 in the adapter body 26and partially within the cylinder 2. Hydraulic nuid under pressure willbe admitted through the connection 9 to the interior of the hydraulicpower cylinder 4 below the piston I3 and the piston will be stationary,since the piston rod 26 is rmly anchored at its lower end beneath thebottom of the engine block I. Therefore, as the iiuid under pressure isadmitted below the piston within the cylinder 4, the cylinder will beforced downwardly, thereby causing the head 5 thereof to force thesleeve or lining 2| downwardly within the engine cylinder 2 until theannular peripheral flange 24 on said sleeve is received within theannular peripheral seat 25 formed in the engine block I about the upperend of the cylinder 2. As the sleeve or lining 2| descends, and shouldthe same be longer than the cylinder 2, its lower end will engage theguide disk 39 and force the same downwardly against the tension of thethree-coil spring 38, thereby guiding and supporting the lower end ofsaid sleeve or lining 2| until it is firmly and xedly positioned withinthe cylinder 2. Y

From the foregoing description, it will be apparent that there has beendevised and provided a highly eflicient form of sleeve inserter adapterwhich will be relatively inexpensive to manufacture and produce.

While the preferred embodiment of the instant invention has beenillustrated and described, it will be understood that it is not intendedto limit the scope of the invention thereto, as many minor changes indetail of construction may be resorted to without departure from thespirit of the invention.
